Lmbo is a more appropriate version of Lmao for people who want to kiss their mother with a clean mouth. It stands for "Laughing my butt off", "Laughing my bones off", "Last mountain bird observatory", "Little mister Bobby Opal", or "Lying my behind off".

alternate way of expressing extreme laughter, to the extent where ones burca falls from ones head. Not enough for one to 'laugh ones ass off', but enough for a burca to fall.
